If gas were $10/gal. I think we would till up our entire back yard and maybe front yard too for vegetables. I think dh would cave and support me in my crazy idea to do urban poultry raising and maybe do bee keeping
(We have a rather small yard).
I would definitely look into the bakfeits trailer, a Croozer or some variation for trips to the grocery.
My girls are at a difficult age when it comes to putting them on a bicycle. They currently go to the same daycare. But next year will be kindergarten and daycare. My near 5 yo dd is practically too big for one of those passenger trailers. I could get a trailabike but then, what do I do with the 2 yo? Not to mention that my dd#1 is such a princess in comparison to dd#2. Dd#2 may actually be riding a bicycle with training wheels before her big sis. I don't know...maybe we would walk to daycare and then the school? (I've been thinking about how to do this right now anyways).
I currently bike to the train for work but drive to the station on bad weather days. I'd probably suck it up for the rain.
Dh already takes public transport. But if that goes up in cost too, I'm not sure what we can do. We live 7 miles and 13 miles from our work place. Totally doable on a bicycle. But we live on the other side of a tunnel. Surface routes around the harbor would mean tacking on a major commute.
